Aircraft/Missile Information
In 1970 a detachment of the 553rd Reconnaissance Wing (later the 554th Reconnaissance Squadron) known as the "Vampires," conducted the first operational QU-22B flights. During a typical mission, the QU-22B orbited near the Ho Chi Minh Trail, picking up signals from Igloo White acoustic and vibration sensing ground units and relaying them to the Information Surveillance Center (or "Task Force Alpha") at Nakhon Phanom Royal Thai Air Force Base.
